Motovario BA52 62.58:1 Bevel Gearbox – 25mm Bore, 90B14

Overview

Motovario BA52 62.58:1 bevel gearbox with a 25mm hollow bore output and 90B14 IEC motor input, configured for compact right-angle power transmission in smaller industrial and OEM drive assemblies.

This version is well suited to applications that need very slow output speed together with maximum torque multiplication, particularly on conveyors, transfer systems, and compact industrial machinery. It gives OEMs and maintenance teams a tidy way to introduce 90° power transmission without moving to an oversized gearbox assembly.

Very High Reduction: At 62.58:1, this version produces very slow output speed together with maximum torque multiplication. That makes it a strong fit for conveyors, transfer equipment, indexing systems, and compact process machinery where highly controlled slow-running performance is required.

The 25mm hollow bore output gives a straightforward shaft-mount arrangement for smaller driven components, helping simplify installation and maintain reliable torque transfer.

The 90B14 IEC motor input is suited to applications needing a larger B14 flange motor connection, giving broader motor compatibility and a more substantial input-side arrangement for compact machinery builds. Being part of the Motovario BA Series platform, it offers a proven modular solution for smaller industrial machines and replacement drive builds.

FAQ

Why choose a 62.58:1 reduction ratio?
A 62.58:1 ratio is a strong option when equipment needs very slow output speed together with maximum torque multiplication. It suits machinery that benefits from substantial speed reduction while keeping drive performance controlled and dependable.

What applications is this configuration suited to?
This gearbox is a strong fit for slow-running conveyors, packaging machinery, transfer drives, indexing systems, and OEM equipment where a 25mm hollow bore and 90B14 motor input are required.

Configuration Notes

Input flange note: the 90B14 IEC motor input uses a 24 x 140 mounting dimension and a compact-face B14 flange arrangement, making it suitable for applications that need a dependable motor connection while still keeping a compact right-angle gearbox format.

Output bore note: the 25mm hollow bore is designed for smaller driven shafts, providing secure shaft engagement and dependable torque transmission in lighter-duty and general industrial applications.

Application example: a good fit for very slow-running conveyors, compact transfer systems, packaging equipment, and OEM machinery where a right-angle gearbox with maximum torque output and a 90B14 motor input is needed.
